ok.

Do you have a mailbox for this "catchall"? I think it should be possible 
to forward this mail either to one of the system users or to a virtual 
user in cyrus (I don't know cyrus, I'm using courier-imap).

Would you mind to post your main.cf (without the comments)?

As far as I understand your setup, you want to get mail for user1/user2 
in their mailboxes, and mail for anything other @virtual.domain1.com to 
... a mailbox of user1 or user2, or a virtual cyrus user? Like so:


mail for user1 at virtual.domain1.com -> delivered to /var/spool/mail/user1
mail for user2 at virtual.domain1.com -> delivered to /var/spool/mail/user2
mail for userx at virtual.domain1.com -> delivered to ???


Is this ok or should _any_ mail for virtual.domain1.com go to a system 
user or a virtual user, e.g.:


mail for user1 at virtual.domain1.com -> delivered to /var/spool/mail/user1
mail for user2 at virtual.domain1.com -> delivered to /var/spool/mail/user1
mail for userx at virtual.domain1.com -> delivered to /var/spool/mail/user1

As I said above, I don't know anything about cyrus. I'm using 
courier-imap and configured it to use virtual mailboxes based on an own 
little database (created and maintained by simple commandline commands).

My email users are totally seperated and independent from the system 
users. An example: I host the domain domainx.de and have there three 
virtual mailboxes and a catchall.

domainx.de is listed in virtual_mailbox_domains (main.cf).

I have also

virtual_mailbox_base = /home/vmail   and
virtual_mailbox_maps = hash:/etc/postfix/virtual

in main.cf.


/etc/postfix/virtual lists these entries for domainx.de:

user1 at domainx.de                        domainx.de/user1/
user2 at domainx.de                        domainx.de/user2/
user3 at domainx.de                        domainx.de/user3/
@domainx.de                             domainx.de/user2/

That means Maidirs are at /home/vmail/domainx.de/userx/
user1, user2 and user3 get their emails (userx at domainx.de) and user2 
gets all other emails to anything at domainx.de in addition to his own ones.

Perhaps this can help you.
